Foreword
The Netherlands Scheme for Certification in the Area of IT Security (NSCIB) provides a third-party
evaluation and certification service for determining the trustworthiness of Information Technology (IT)
security products. Under this NSCIB, TrustCB B.V. has the task of issuing certificates for IT security
products, as well as for protection profiles and sites.
Part of the procedure is the technical examination (evaluation) of the product, protection profile or site
according to the Common Criteria assessment guidelines published by the NSCIB. Evaluations are
performed by an IT Security Evaluation Facility (ITSEF) under the oversight of the NSCIB Certification
Body, which is operated by TrustCB B.V. in cooperation with the Ministry of the Interior and Kingdom
Relations.
An ITSEF in the Netherlands is a commercial facility that has been licensed by TrustCB B.V. to
perform Common Criteria evaluations; a significant requirement for such a licence is accreditation to
the requirements of ISO Standard 17025 “General requirements for the accreditation of calibration and
testing laboratories”.
By awarding a Common Criteria certificate, TrustCB B.V. asserts that the product or site complies with
the security requirements specified in the associated (site) security target, or that the protection profile
(PP) complies with the requirements for PP evaluation specified in the Common Criteria for
Information Security Evaluation. A (site) security target is a requirements specification document that
defines the scope of the evaluation activities.
The consumer should review the (site) security target or protection profile, in addition to this
certification report, to gain an understanding of any assumptions made during the evaluation, the IT
product's intended environment, its security requirements, and the level of confidence (i.e., the
evaluation assurance level) that the product or site satisfies the security requirements stated in the
(site) security target.

Recognition of the Certificate
Presence of the Common Criteria Recognition Arrangement (CCRA) and the SOG-IS logos on the
certificate indicates that this certificate is issued in accordance with the provisions of the CCRA and
the SOG-IS Mutual Recognition Agreement (SOG-IS MRA) and will be recognised by the participating
nations.
International recognition
The CCRA was signed by the Netherlands in May 2000 and provides mutual recognition of certificates
based on the Common Criteria (CC). Since September 2014 the CCRA has been updated to provide
mutual recognition of certificates based on cPPs (exact use) or STs with evaluation assurance
components up to and including EAL2+ALC_FLR.
For details of the current list of signatory nations and approved certification schemes, see
http://www.commoncriteriaportal.org.
European recognition
The SOG-IS MRA Version 3, effective since April 2010, provides mutual recognition in Europe of
Common Criteria and ITSEC certificates at a basic evaluation level for all products. A higher
recognition level for evaluation levels beyond EAL4 (respectively E3-basic) is provided for products
related to specific technical domains. This agreement was signed initially by Finland, France,
Germany, The Netherlands, Norway, Spain, Sweden and the United Kingdom. Italy joined the SOG-IS
MRA in December 2010.
For details of the current list of signatory nations, approved certification schemes and the list of
technical domains for which the higher recognition applies, see https://www.sogis.eu.

1 Executive Summary
This Certification Report states the outcome of the Common Criteria security evaluation of the NXP
SN300 Series - Secure Element SN300_SE B1.1 J9. The developer of the NXP SN300 Series -
Secure Element SN300_SE B1.1 J9 is NXP Semiconductors Germany located in Hamburg, Germany
and they also act as the sponsor of the evaluation and certification. A Certification Report is intended
to assist prospective consumers when judging the suitability of the IT security properties of the product
for their particular requirements.
The TOE is a Security Integrated Circuit Platform for operating systems and applications with high
security requirements. The SN300x Single Chip Secure Element and NFC Controller Series combines
on a single die an Embedded Secure Element and a NFC Controller (the "x" in SN300x indicates the
type of the SN300 series, representing for example the NFC Controller configuration). The two
subsystems are called "SN300_SE" and "SN300_NFC". The NFC Controller is not part of the TOE.
The Embedded Secure Element SN300_SE is based on a Flash-based secure microcontroller
platform.
The TOE was previously evaluated by SGS Brightsight B.V. located in Delft, The Netherlands and was
certified under the accreditation of TÜV Rheinland Nederland on 13-05-2022 (CC-22-0441513). The
current evaluation of the TOE has also been conducted by SGS Brightsight B.V. and was completed
on 04-12-2023 with the approval of the ETR. The certification procedure has been conducted in
accordance with the provisions of the Netherlands Scheme for Certification in the Area of IT Security
[NSCIB].
The major changes from previous evaluations are:
- Updated UGM (User Guidance Manual). Associated update to ST
- Added site for secure destruction
The certification took into account that the security evaluation reused the evaluation results of
previously performed evaluations. A full, up-to-date vulnerability analysis has been made, as well as
renewed testing.
The scope of the evaluation is defined by the security target [ST], which identifies assumptions made
during the evaluation, the intended environment for the NXP SN300 Series - Secure Element
SN300_SE B1.1 J9, the security requirements, and the level of confidence (evaluation assurance
level) at which the product is intended to satisfy the security requirements. Consumers of the NXP
SN300 Series - Secure Element SN300_SE B1.1 J9 are advised to verify that their own environment
is consistent with the security target, and to give due consideration to the comments, observations and
recommendations in this certification report.
The results documented in the evaluation technical report [ETR] 1 for this product provide sufficient
evidence that the TOE meets the EAL4 augmented (EAL4+) assurance requirements for the evaluated
security functionality. This assurance level is augmented with ALC_DVS.2 (Sufficiency of security
measures) and AVA_VAN.5 (Advanced methodical vulnerability analysis).
The evaluation was conducted using the Common Methodology for Information Technology Security
Evaluation, Version 3.1 Revision 5 [CEM] for conformance to the Common Criteria for Information
Technology Security Evaluation, Version 3.1 Revision 5 [CC] (Parts I, II and III).
TrustCB B.V., as the NSCIB Certification Body, declares that the evaluation meets all the conditions
for international recognition of Common Criteria Certificates and that the product will be listed on the
NSCIB Certified Products list. Note that the certification results apply only to the specific version of the
product as evaluated.

2 Certification Results
2.1 Identification of Target of Evaluation
The Target of Evaluation (TOE) for this evaluation is the NXP SN300 Series - Secure Element
SN300_SE B1.1 J9 from NXP Semiconductors Germany located in Hamburg, Germany.
The TOE is comprised of the following main components:
Delivery
item type
Identifier Version
Hardware SN300_SE B1.1
Software
FactoryOS 1.11.3
BootOS (ROM) 1.11.1
Flash Driver Software (FlashROM) 1.11.2
To ensure secure usage a set of guidance documents is provided, together with the NXP SN300
Series - Secure Element SN300_SE B1.1 J9. For details, see section 2.5 “Documentation” of this
report.
For a detailed and precise description of the TOE lifecycle, see the [ST], Chapter 1.3.3.
2.2 Security Policy
The TOE maintains:
• Memory encryption and masking mechanisms are implemented to preserve confidentiality of data
• The hardware embeds sensors, which ensure proper operating conditions of the device.
• Integrity protection of data and code involves error correction and error detection codes, light
sensing and other security functionality.
• The IC hardware is shielded against physical attacks.
• The lockstep (redundant) CPU ensures protection against faults in the CPU.
• Hardware to serve with True Random Numbers
2.3 Assumptions and Clarification of Scope
2.3.1 Assumptions
The assumptions defined in the Security Target are not covered by the TOE itself. These aspects lead
to specific Security Objectives to be fulfilled by the TOE-Environment. For detailed information on the
security objectives that must be fulfilled by the TOE environment, see section 4.2 of the [ST].
2.3.2 Clarification of scope
The evaluation did not reveal any threats to the TOE that are not countered by the evaluated security
functions of the product.
The SN300x chip combines on a single die an Embedded Secure Element and an NFC Controller.
The two subsystems are called "SN300_SE" and "SN300_NFC". Both subsystems use a shared
Power Management Unit ("SN300_PMU"). Only the “SN300_SE” is part of the TOE (see the figure in
section 2.4).
Although the TOE has different dedicated cryptographic co-processors (e.g. PKC, AES, DES), the
TOE has no security claims regarding cryptographic functionality.
Note that SN300x without any Security IC Embedded Software for the TOE is available for NXP
internal use only

2.5 Documentation
The following documentation is provided with the product by the developer to the customer:
Identifier Version
SN300_SE Information on Guidance and Operation Revision 1.6
SN300 family; Single Chip Secured (NFC) controller, Product data sheet. Revision 1.E
SN300V TOE Identification, Data sheet addendum Revision 1.3
SN300_SE Programmer's Manual, Application Note Revision 0.22
Arm® Cortex®-M33 Processor, Technical Reference Manual Revision r1p0
2.6 IT Product Testing
Testing (depth, coverage, functional tests, independent testing): The evaluators examined the
developer’s testing activities documentation and verified that the developer has met their testing
responsibilities.
2.6.1 Testing approach and depth
The developer performed extensive testing on functional specification, subsystem and SFR-enforcing
module level. All parameter choices were addressed at least once. All boundary cases identified were
tested explicitly, and additionally the near-boundary conditions were covered probabilistically. The
testing was largely automated using industry standard and proprietary test suites. Test scripts were
used extensively to verify that the functions return the expected values.

For the testing performed by the evaluators, the developer provided samples and a test environment.
The evaluators reproduced a selection of the developer tests, as well as a small number of test cases
designed by the evaluator.
2.6.2 Independent penetration testing
The independent vulnerability analysis performed was conducted along the following steps:
• When evaluating the evidence in the classes ASE, ADV and AGD the evaluator considered
whether potential vulnerabilities could already be identified due to the TOE type and/or
specified behaviour in such an early stage of the evaluation.
• For ADV_IMP a thorough implementation representation review was performed on the TOE.
During this attack-oriented analysis the protection of the TOE was analysed using the
knowledge gained from all evaluation classes. This resulted in the identification of (additional)
potential vulnerabilities. This analysis used the attack methods in [JIL-AM] and [JIL-AAPS].
• All potential vulnerabilities were analysed using the knowledge gained from all evaluation
classes and information from the public domain. A judgment was made on how to assure that
these potential vulnerabilities are not exploitable. The potential vulnerabilities were addressed
by penetration testing, a guidance update or in other ways that are deemed appropriate.
The test effort in the baseline evaluation expended by the evaluators was 15 weeks. During that test
campaign, 6% of the total time was spent on physical Attacks, 34% Perturbation attacks, 54% on side-
channel testing, and 6% on logical tests.
The additional test effort in the re-certification expended by the evaluators was 8 weeks. During that
test campaign, 0% of the total time was spent on physical Attacks, 25% Perturbation attacks, 75% on
side-channel testing, and 0% on logical tests.
2.6.3 Test configuration
The configuration of the sample used for independent evaluator testing and penetration testing was
the same as described in the [ST]. For some tests, testing was performed on an earlier revision of the
TOE. The assurance gained from testing on an earlier revision has been assessed to be valid for the
final TOE version, because the changes introduced were minimal and did not have an impact on the
TSF.
2.6.4 Test results
The testing activities, including configurations, procedures, test cases, expected results and observed
results are summarised in the [ETR], with references to the documents containing the full details.
The developer’s tests and the independent functional tests produced the expected results, giving
assurance that the TOE behaves as specified in its [ST] and functional specification.
No exploitable vulnerabilities were found with the independent penetration tests.
For composite evaluations, please consult the [ETRfC] for details.
2.7 Reused Evaluation Results
This is a re-certification. Documentary evaluation results of the earlier version of the TOE have been
reused, but vulnerability analysis and penetration testing has been renewed.
There has been extensive reuse of the ALC aspects for the sites involved in the development and
production of the TOE, by use of site certificates and their associated Site Technical Audit Reuse
reports.
No sites have been visited as part of this evaluation.

2.8 Evaluated Configuration
The TOE is defined uniquely by its name and version number NXP SN300 Series - Secure Element
SN300_SE B1.1 J9.
2.9 Evaluation Results
The evaluation lab documented their evaluation results in the [ETR], which references an ASE
Intermediate Report and other evaluator documents. To support composite evaluations according to
[COMP] a derived document [ETRfC] was provided and approved. This document provides details of
the TOE evaluation that must be considered when this TOE is used as platform in a composite
evaluation.
The verdict of each claimed assurance requirement is “Pass”.
Based on the above evaluation results the evaluation lab concluded the NXP SN300 Series - Secure
Element SN300_SE B1.1 J9, to be CC Part 2 extended, CC Part 3 conformant and to meet the
requirements of EAL 4 augmented with ALC_DVS.2 and AVA_VAN.5. This implies that the product
satisfies the security requirements specified in Security Target [ST].
The Security Target claims ’strict’ conformance to the Protection Profile [PP].
2.10 Comments/Recommendations
The user guidance as outlined in section 2.5 “Documentation” contains necessary information about
the usage of the TOE.
In addition, all aspects of assumptions, threats and policies as outlined in the Security Target not
covered by the TOE itself must be fulfilled by the operational environment of the TOE.
The customer or user of the product shall consider the results of the certification within his system risk
management process. For the evolution of attack methods and techniques to be covered, the
customer should define the period of time until a re-assessment for the TOE is required and thus
requested from the sponsor of the certificate.
The strength of the cryptographic algorithms and protocols was not rated in the course of this
evaluation. This specifically applies to the following proprietary or non-standard algorithms, protocols
and implementations: <None>.
